ADS8317IBDGKR

Analog To Digital Converters (ADC) Overview

The ADS8317IBDGKR is a 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 250 kSPS and supports both differential and single-ended input configurations. The device functions within an analog and digital supply voltage range of 2.7 V to 5.5 V, consuming approximately 10 mW of power. It features a serial peripheral interface (SPI) compatible with 3-wire communication protocols. Key performance metrics include a signal-to-noise ratio (SNR) of 84.8 dB, a differential nonlinearity (DNL) of -1/2 LSB, and an integral nonlinearity (INL) of +/- 2 LSB. The component is housed in an 8-pin VSSOP package and is rated for operation between -40°C and +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix DGKR corresponds to the tape-and-reel packaging format when sourcing components. Confirm that the IB designation indicates the extended industrial temperature range suitable for your operational environment. Ensure compatibility with external reference voltage requirements as the device utilizes an external reference configuration rather than an internal one.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 16-bit resolution and moderate speed is required without the complexity of multi-channel devices. Consider the VSSOP-8 package constraints regarding PCB space and thermal dissipation capabilities. Evaluate system power budgets against the 10 mW typical consumption at full sampling rates to ensure compliance with energy efficiency targets.
